I cannot change the Icon Style, Icon Size, Visibility, Mouse settings in the Options dialog. Options cannot be selected and applied.
FreeBSD 12.2 RELEASE-p10 amd64, KDE Plasma 5.22.5, KDE Frameworks 5.86, Qt 5.15.2, Libreoffice 126.96.36.199
A workaround until this is fixed is to select the item using the up down arrows then press return.
